If all of them use the same outgoing line, can they be aggregated? If so, to what? If not, why not?

Thus we can do a supernetting here and keep a supernet address as :- $57.6.96.0/19$ prashant jha 1 answered Mar 18, 2019 prashant jha 1 comment Share Follow See all 0 reply Please log in or register to add a comment.
